CRUX-CONTROLLED MECHANISM.

Specification of Letters Patent.

Patented July 28, 1908.

Original application filed July 22, 1907, Serial No. 384,952. Divided and this application filed November 6, 1907 Serial No. 400,993.

To all whom it may concern:

Be it known that I, THOMAS V. SKELLY, a citizen of the United States of America, and a resident of Chicago, county of Cook, State of Illinois, have invented certain new and useful Improvements in Check Controlled Mechanisms, of which the following is a specification.

The main objects of this invention are to provide an improved construction for check controlled mechanisms; to provide a mechanism of this class which is particularl adapted for application to a machine which may be set in operation through the rotation of a crank; to provide an improved form of rotatin clutch for coin operated devices, in

which t e coin itself is the means for throwing the clutch to ermit the operation of the mechanism. T ese objects are accomplished b. the device shown in the accompanying rawings, which illustrate a specific embodiment of this invention, the particular arrangement of parts being such as is suitable for check controlled mechanism when applied to phonograph operating mechanism such as is shown in my co-pending application, Serial No.i384,952, filed July 22nd, 1.907

' of which the present application is a division.

Fi ure 1 o the drawings is adetail of the cran shaft and check controlled clutch, by

means of which is accom lished theoperation of the machine to W oh the coin con,

' trolled mechanism is attached, the parts which are mounted on said shaft being shown in section. Fig. 2 is a side elevation of clutch members,-showing the same in engagement with each other, Fi 3 is an elevation of the same, viewed from t e right of Fig. 2, and showing some of the adjacent mechanism. Fig. 4 is a similar elevation, viewed from the left of Fig. 2, and corresponding to a section on the line 44 of Fig. 1. Fi 5. is a section on the line 55 of Fig. 2, sai section being in the plane of separation between the two clutch members.

7 tion of the trip lever. which prevents the opshown in the drawings, the parts of the mechanism are so arranged as to control the operation of a machine and be in turn operated by means of an operating shaft 14. The

Fig.6 is an elevashaft 14 is provided with a crank 19, by which it may be rotated by the operator. The shaft 14 also has mounted thereon a air of clutch members 26 and 27 for control ing the operation of the machine, as will hereinafter ap ear.

The riving member 26 of the clutch is rigidly secured to the shaft 14 and has a recess 28 in its periphery, whose function will be hereinafter described. The driven mem-' ber 27 is loosel mounted upon theshaft 14, and is provided with a helical cam surface 29 and an annular series of ratchet teeth 30.

The s ring pawl 31 (Figs. 3 and 4) engages the rate et teeth 30 and prevents the rotation of the member 27 except in the normal right-handed direction. The member 27 is also rovided with a peripheral cam surface 32 adiacent to the ratchet teeth 30.

The member 26 has pivotall mounted thereon at 33 a dog or lever 34 w ich carries a tongue 35 extending through an opening in the member 26and being movable into and out of engagement with a recess 36 in the member 27. The spring 37 normally urges the tongue 35 of the'dog 34 toward the memtially in the same plane with the member 26. The arm 38 partly encircles the peri hery of the member 26 and is provided with an inclined wedge surface 40 adapted to engage on the supporting frame and lies substani the inclined end 41 of the dog 34 and cause the detent 35 to be retracted to prevent it from entering the recess 36 when the shaft 14 is turned in its normal right hand direction, as indicated by the arrows on Figs. 3 and 4. The arm 38 is normally or ed toward the periphery of the member 26 y means of the spring 42. The arm 38 is provided with a projecting lug 43 which extends into the cam groove 32 of the member 27 and rests upon the cam surface at the bottom of said groove. This cam is of suitable form. to hold the arm 38 clear of the member 26 While the latter is rotating. This lug 43 also serves as a stop for engaging the stop shoulder 43' in the groove 32 to stop the member 27 in its nor-1 mal initial position when the same has been rotated through a complete revolution.

The coin chute 44 is mounted in the supporting frame with its discharge end op osed to the periphery of the member 26. hen the arts are in their normal position of rest, as ill ustrated in Fig. 3, the recess 28 of the 5 member 26 will be in alinement with the coin chute 44, so that a coin inserted in said chute will be deposited in said recess or seat 28.
